"success of its UK NFC trial"
That wouldn't have *anything* to do with the 'free money' given to the guinea pigs, would it?
Of course not.
How cynically foolish of me to think that anyone's opinion could be swayed by a nice shiny new phone, and some 'credit' to spend.
Does anyone have a breakdown of the spending profiles of the guinea pigs (without any personally identifiable data, of course!) to see just what proportion (if any!) was spent on BOOZE?
